TSNAdb: A Database for Tumor-specific Neoantigens from Immunogenomics Data Analysis / 基因组蛋白质组与生物信息学报·英文版

Tumor-specific neoantigens have attracted much attention since they can be used as biomarkers to predict therapeutic effects of immune checkpoint blockade therapy and as potential targets for cancer immunotherapy. In this study, we developed a comprehensive tumor-specific neoantigen database (TSNAdb v1.0), based on pan-cancer immunogenomic analyses of somatic mutation data and human leukocyte antigen (HLA) allele information for 16 tumor types with 7748 tumor samples from The Cancer Genome Atlas (TCGA) and The Cancer Immunome Atlas (TCIA). We predicted binding affinities between mutant/wild-type peptides and HLA class I molecules by NetMHCpan v2.8/v4.0, and presented detailed information of 3,707,562/1,146,961 potential neoantigens generated by somatic mutations of all tumor samples. Moreover, we employed recurrent mutations in combination with highly frequent HLA alleles to predict potential shared neoantigens across tumor patients, which would facilitate the discovery of putative targets for neoantigen-based cancer immunotherapy.

The comparing study between subchronic toxicity and local implantation response of sodium hyaluronan gels for different application / 生物医学工程学杂志

According to the requirements of ISO10993-11.2006 and ISO10993-6:r2007 standards, we used SD rats for evaluating the subchronic systemic toxicity and local implantation response of two kinds of sodium hyaluronan gels with different application. The results of 90d subchronic toxicity study by intraperitoneal route showed that the animals of the tested group and control group grew normally. There were no differences in the increases of the body weight, haematological index and clinical biochemistry indexes. The examination of gross pathology and histopathology revealed no abnormal changes caused by the test substance during the process. But there was different degree test article residual in the body of the animals at the end of the experiment. It was observed in the local subcutaneous implantation that at the early stage, gel A had mild inflammatory response, cysts were seen clearly, and new blood capillaries were visible at local area. Later, the wall got thinner and dense with little tissue reaction. Gel B also had mild inflammatory response earlier, but it totally disappeared after 14 days of implantation. It can be concluded that the gel products with different characteristics decided its degradation and metabolic process in the body of the test animals and therefore the areas of application of the products clinically. Meanwhile, we compared the evaluation method of subchronic systemic toxicity and local implantation response in risk assessment, providing reference for the choice of biological safe testing.

Association between the plasma homocysteine level,gene polymorphism of N5,N10 methylene tetrahydrofolate reductase and Binswanger's disease / 临床神经病学杂志

0.05).Conclusions The level of plasma Hcy in BD patients are higher than that of in the controls.Hyperhomocysteine may take part in the pathogenesis of BD, but the MTHFR gene C677T genotypes are not associated with BD.

Clinical, hemorheology, TCD and ABR features in senile sudden deafness / 临床神经病学杂志

Objective To investigate the clinical, hemorheology, transcranial Doppler (TCD) and auditory brainstem evoked response (ABR) features in senile sudden deafness.Methods The clinical manifestations, hemorheology, TCD, and ABR data in 82 patients with senile sudden deafness were analyzed retrospectively.Results (1) The primary symptoms mainly included tinnitus (65.9%) and vertigo (56.1%), which mostly occurred at daytime (53.7%).(2) Most of the patients had risk factors of arteriosclerosis such as hypertension (75.6%), diabetes (59.8%) and so on. These patients had more serious deafness.(3) There was no obvious relationship between high blood viscosity (61% of the patients) and the degree of deafness. (4) 85.4% of senile sudden deafness patients indicated vertebral-basilar artery insufficiency in TCD. There was a positive correlation between blood supply and degree of deafness. (5) The abnormal rate of ABR was 100%. WaveⅠdisappeared in most patients, which showed serious damage of auditory nerve. Disappearing of waveⅠ, Ⅲ, Ⅴ and Ⅰ～Ⅲ, Ⅲ～Ⅴ, Ⅰ～Ⅴ delitescence period delaying might be complicated with the damage of the structure of the brainstem and cochlea.Conclusions The morbidity and degree of senile sudden deafness are associated with insufficiency of blood supply of internal ears. TCD and ABR are sensitive and reliable methods in diagnosis, progression and prognosis of senile sudden deafness.

Cognitive Therapy in Combination with Electromyographic Feedback in Treatment of Diabetes Patients with Depression after Cerebral Infarction / 中国临床心理学杂志

Objective: To study the effect of cognitive therapy in combination with electromyographic feedback therapy on diabetes patients with depression after cerebral infarction. Methods: 60 patients were randomly divided into study group (n=30) and control group (n=30) , The former received cognitive therapy and electromyographic feedback trainings in addition to regular medication. All patients were evaluated with Hamilton Depression Rating Scales (HAMD),Neurological Function Deficit scale(NFD)?Barthel Index(BI) and FPG (free plasma glucose), 2HPG (plasma glucose after 2 hours of a meal). Results: The improvement of study group was greater than the control group(P
